DIMERIC CYANOACRYLATE COMPOUNDS AS RED-SHIFTED UV ABSORBERS

Dimeric cyanoacrylate compounds of Formula (I) and Formula (II) having low volatility are provided for absorption of radiation in the UV-A region of the electromagnetic spectrum, which encompasses wavelengths between 320 nm and 400 nm. These compounds can also be blended with other UV absorbers and...

Beschreibung
Zusammenfassung:	Dimeric cyanoacrylate compounds of Formula (I) and Formula (II) having low volatility are provided for absorption of radiation in the UV-A region of the electromagnetic spectrum, which encompasses wavelengths between 320 nm and 400 nm. These compounds can also be blended with other UV absorbers and UV stabilizers and are useful as stabilizers of materials subject to degradation by UV radiation. An exemplary compound includes formula: La présente invention concerne des composés dimériques de cyanocrinolate de formule (I) et de formule (II) présentant une faible volatilité pour l'absorption de rayonnement dans la région de rayonnement UV A du spectre électromagnétique, qui englobe des longueurs d'onde comprises entre 320 nm et 400 nm. Ces composés peuvent également être mélangés avec d'autres absorbants UV et stabilisateurs d'UV et sont utiles en tant que stabilisateurs de matériaux sujets à la dégradation par le rayonnement UV.
